FIELD OF THE INVENTION

The present invention relates to systems and methods for publishing and displaying digital materials.

DESCRIPTION OF THE RELATED ART

There are several solutions on the market for either publishing digital course materials or displaying digital course materials, but no solutions that address both. Tools like Adobe's InDesign are configured to help one create materials for publication electronically, while tools like Adobe's Digital Editions, VitalSource, CourseSmart, and BookWorm are designed. to display the publications. These systems are proprietary and require agreements with each entity. Moreover, they do not allow an institution to use one system to publish and display content in a relevant way.

One problem that exists with VitalSource and other conventional tools is that users arc often forced to register with a system and create a user name and password. Another problem with conventional tools is the client download issue. Many of the readers (display of content) require a client download. This means a user has to download and install something in order to use the product. This is replete with issues including how many licenses a user gets.

Currently, there is no system in existence that offers an individual or institution the ability to: (i) load, publish and display content; (ii) create users from existing databases; (iii) be accessible from any browser; and (iv) employ the electronic publication (ePub) standard. ePub is a free and open e-hook standard by the International Digital Publishing Forum (IDPF). In general, ePub is designed for reflowable content such that the text display can be optimized for the particular display device.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

The present invention is directed toward systems and methods for publishing and displaying digital materials, for example, in a learning environment. The systems and methods set forth herein can include embedded audio, video, and Adobe Flash interactive applications within the reader experience. This enables the content to be better absorbed by auditory and visual learners than the standard “book” experience.

In some embodiments, the system offers several choices for users to access the learning materials outside of the core reader function. Such choices include: (i) a standard, static ePub tile that can be accessed by any of the handheld readers which utilize this format; (ii) a static PDF which can be downloaded so that users can access content without an interact connection as well as a formatted, print-friendly version; and (iii) MP3 audio files that can be downloaded for users to access the materials as an audio book, In further embodiments, the system provides a web-based reader that allows users to add, markup notation to the content through tools for highlighting, bookmarking and notation. The markup tools help the user mirror the ability to markup content as they would in a print textbook. Highlights and notes are saved and available for the user to access in a summary section.

Various systems and methods of the invention provide electronic delivery of “published” content to provide for greater flexibility and portability for the user learning environment based on each individual user's unique needs. Some embodiments provide the ability for consumers to annotate, mark up, and/or organize content electronically in a way that mimics traditional non-digital form and practices, and provides additional capabilities not available in a traditional non-digital form. In addition, some embodiments provide an increased ability to aggregate or separate content to maximize relevancy to the context of the delivery. This allows publishers to creatively define unique content by aggregating disparate pieces of content from a variety of sources into a single delivery (e.g., virtual books). This also allows for individual pieces of content to be delivered to the customer based on the context of the demand. This further allows for real-time dynamic assembly and delivery of relevant content based on the context of the demand.

An additional aspect of the systems and methods for publishing and displaying digital materials set forth herein includes a reduced time to market for published content to availability for delivery. In many cases, the time to market can be reduced to such extent that it can meet or nearly meet the definition of real-time. Certain embodiments further provide ease of integration into various disparate operating environments and consuming or producing systems.

The above-described features can enable publication and delivery of highly relevant content based on a dynamically changing demand context of the consumer system. or person) in real or near real-time. This, in turn, can support innovative and creative learning solutions, e.g., integrating into an online study hall. In such an example, the library may listen in and offer up snippets or full content items to the study hall participants based on a changing context of the study hall conversation. In addition, a publisher could be part of the conversation, publish content and make it available immediately for integration into this and other conversations.

As set forth above, there is currently no system in the market that offers an individual or institution the ability to: (i) load, publish and display content; (ii) create users from existing databases; (iii) be accessible from any browser; and (iv) employ the ePub standard. The various embodiments of the invention solve this problem. In addition, the systems and methods described herein provide an institution the ability to automatically create user accounts for users within the institution. In some embodiments, the system/method is fully integrated with a Campus Management module allowing users to be pulled and created from existing data. By way of example, when a student is registered in a college associated with the systems and methods set forth herein, they are automatically registered with the Campus Management module. As such, an opportunity is afforded to seamlessly pull users from the college into the Campus Management module.

Using the system, an institution, author, or publisher can upload content via the ePub standard. The system indexes the material and displays it to one's readers/users in a meaningful way with a table of contents. Furthermore, the content will be searchable and will offer the user the ability to highlight, take notes and make bookmarks. This provides users with a “one stop shop” for their publication, display and user creation needs.

Another problem with conventional tools is the client download issue, wherein a user has to download and install something in order to use the product. This is replete with issues including how many licenses a user gets. The systems described herein are browser-based and do not require a download; accordingly, users can access published materials from any computer with a browser and interact connectivity, anywhere and at any time.

The systems and methods of the invention use the ePub standard. Consequently, they are digital rights management (DRM) free such that users can interact with the materials in ways they prefer. DRM comprises access control technology that may be employed to impose limitations on the use of digital content and devices. Because the systems and methods of the invention are DRM-free, users may download and save, print, and send content to a mobile device like a Kindle or iPhone. By employing the ePub standard, it is very easy to repurpose the content for other online uses like mobile applications.

According to various embodiments of the invention, the systems and methods may be employed to: (i) publish, download, print, send to a mobile device and manage user database for any publishable item including documents, spreadsheets, books, magazines. etc.; (ii) communicate with any user base; (iii) grow and share collaborative communities; (iv) customize, publish and share material with others; and (v) publish digital offerings.

FIG. 1 is a platform diagram of an example system for publishing and displaying digital materials, in accordance with an embodiment of the invention. The illustrated system platform 10 comprises various components including content item bookshelf 12, content item reader 14, editorial application 16, administration application 18, analytics 20, security and single sign-on (SSO) 22, content repository 24, public RESTful application programming interfaces (APIs) 26, database 28 and mobility application 30. The security and SSO 22, content repository 24, and public RESTful APIs 26 are in communication with an external system 32.

A software application may reside on various components of the system platform 10, the software application comprising computer executable program code storable on a non-transitory computer readable medium, the computer executable program code configured for performing various functions. In particular, the software application includes an electronic publication (ePub) publishing module comprising a mechanism for publishers to upload ePub files. During the upload process, the publisher may also choose to upload supporting content such as audio files, video files, Portable Document Formats (PDFs), addendums, and content in various other formats. According to some embodiments, each ePub file goes through an indexing process to support full-text search. The file may then he broken down into a new structure that allows for easy web loading. The publisher can then choose when to publish their content, thereby making the content visible in the public bookshelf.

The software application may further comprise a user management module. In some embodiments, the user management module can provide three ways to add/edit/remove end users from the system. First, an administrator can manually add/edit/remove end users using a “User Management” interface. Second, an administrator may configure the platform 10 to use an external user management system. 32 such as Lightweight Directory Access Protocol (LDAP). Third, the administrator may elect to integrate through the system's public RESTful APIs 26.

The software application also comprises a bookshelf module. In operation, an end user's first entry point into the system takes them to the bookshelf. By default, the end user will have one bookshelf or shelf when initially entering the system. The user can also create more shelves to organize his or her content at any time in order to create a logical grouping of content. When searching for public content, an end user will need to perform a “check out” in order to move content to one of the shelves. Once a “check out” has been performed, the end user can interact with the content in various ways including, but not limited to, reading content, annotating content, downloading content, printing content, and searching within content.

In some embodiments o the invention, the software application may further comprise a reading content module. In general, an end user can only read content once they have been “mapped” to the content. Mapping is essentially binding a user to an instance on the content, which can be achieved in one of two ways. The first option occurs when a user “checks out” content to a selected bookshelf. The second option is through a public RESTful API 26. The mapping process allows the end user to read the content.

The software application may further comprise an annotating content module. When reading the content, the end user may choose to annotate the content. There are three different types of annotations: (i) Highlights, (ii) Notes, and (iii) Bookmarks.

An end user can select text, and then choose to annotate the selected text. The end user also has the option of selecting an annotation color. Once annotated, the end user has a visual clue in the content and in the summary section, which provides the user with the capabilities of managing the annotation (e.g., removing and editing the annotation).

The software application may further comprise a downloading center module. An end user may choose to download content in a specific forty at to a specific device. The format is generally decided during a publishing process when the publisher uploaded the content. The end user is able to either select one of the publisher's formats, the original ePub format, or selectable sections from the content n ePub form. Once the format has been selected, the end user may select a device for downloading. The system may support various kinds of devices, including, but not limited to: (i) the end user's PC,) Amazon Kindle Sony Reader, (iii) iPhone, (iv) iPad, and (v) various other devices.

The system may provide the end user with a step-by-step wizard for enabling a trouble free download.

According to some embodiments, the software application further comprises a searching module, whereby an end user can perform two types of searches. The first type comprises searching across content, or in the public library, for content that matches the search terms. The second type comprises searching within a specific content, which provides anchor links for the end user to interact with the search results and view them when clicked. Searching can also include related content such as annotations, shared content, and supporting content.

The software application may further comprise a sharing module, whereby an end user can choose to share the annotations and comments he or she made with respect to the content. The end user can also choose sharing properties such as audience, permissions, and other selected properties. All shared content will become available in the public bookshelf.

In some embodiments, the software application may further comprise a virtual content module. The system provides the capability to create a virtual content item. An end user can select parts of different content items into one virtual content item. The virtual content item can then be placed onto an end user's bookshelf for easy access.

According to various embodiments described herein, the standards employed may include, but are not limited to, Open Publication Structure (OPS) 2.0 v1.0, Open Packaging Format (OPF) 2.0 v1.0, and OEBPS Container Format (OCF) 1.0.

The systems described herein include primary instructional digital materials for course reading assignments and activities, a browser-based reader to display digital content, and integration with college systems and student portals. The digital materials may be displayed on a variety of devices—including MP3 players and PDAs—and may be designed with students and academic outcomes in mind. As discussed below, such systems solve several problems and create a number of opportunities.

The systems provide a cost savings to students because the digital instructional materials replace print textbooks published by third parties. Digital materials eliminate costs associated with physical inventory and shipping. The systems of the invention may also avoid the constraints of licensing digital content from third parties. Third parties are typically very concerned about piracy of their digital materials such that they compensate by incorporating digital rights management (DRM) into their products. DRM usually limits the number of installations and restricts the print function. Also, since publishers do not see digital content as a major source of revenue, they do not invest much in features and functionality.

In some embodiments of the invention, the digital materials are developed on a work-for-hire basis such that the copyrights are owned by the university engaging the content developers. This allows the university to control the revision cycle so that they no longer have to update materials simply because a third party decides it is time to roll out a new edition. As such, the university can correct and revise in its discretion, as and when needed or appropriate.

Various embodiments of the invention are based upon an ownership model for digital materials. By contrast, most digital content is licensed, not owned. According to embodiments where digital content is associated with an ownership model, users/students pay a one-time fee and may use the content any way, any time, and in as many variations as they wish. The adoption of ePub as the standard for document conversion allows the reflowing of content regardless of device (i.e. content will display appropriately on a Kindle, an iPAD, etc., unlike a static file like .pdf). It also allows the simplification of production output by converting to other formats (.pdf, rtf) as desired by the user.

In some embodiments, the system includes essential reading materials (chapters) and other assets (e.g., audio files) that cater to specific learning styles. Based on principles of universal design, the system may encompass alternative materials or students who have disabilities, e.g., visual and neurological impairments. The system may also include a reader that gives students tools to manage their content: not only highlight, notes, and bookmarks, but also a way to organize the content by chapter. And, unlike current versions of Kindle and other readers, the system supports color.

As used herein, the term “set” may refer to any collection of elements, whether finite or infinite. The term “subset” may refer to any collection of elements, wherein the elements are taken from a parent set; a subset may be the entire parent set. The term “proper subset” refers to a subset containing fewer elements than the parent set. The term “sequence” may refer to an ordered set or subset. The terms “less than,” “less than or equal to,” “greater than,” and “greater than or equal to,” may be used herein to describe the relations between various objects or members of ordered sets or sequences; these terms will he understood to refer to any appropriate ordering relation applicable to the objects being ordered.

The term “tool” can be used to refer to any apparatus configured to perform a recited function. For example, tools can include a collection of one or more modules and can also be comprised of hardware, software or a combination thereof

Thus, for example, a tool can be a collection of one or more software modules, hardware modules, software/hardware modules or any combination or permutation thereof. As another example, a tool can be a computing device or other appliance on which software runs or in which hardware is implemented.

As used herein, the term “module” might describe a given unit of functionality that can be performed in accordance with one or more embodiments of the present invention. As used herein, a module might be implemented utilizing any form of hardware, software, or a combination thereof. For example, one or more processors, controllers, ASICs, PLAs, PALs, CPLDs, FPGAs, logical components, software routines or other mechanisms might be implemented to make up a module. In implementation, the various modules described herein might be implemented as discrete modules or the functions and features described can be shared in part or in total among one or more modules. In other words, as would be apparent to one of ordinary skill in the art after reading this description, the various features and functionality described herein may be implemented in any given application and can be implemented in one or more separate or shared modules in various combinations and permutations. Even though various features or elements of functionality may be individually described or claimed as separate modules, one of ordinary skill in the art will understand that these features and functionality can be shared among one or more common software and hardware elements, and such description shall not require or imply that separate hardware or software components are used to implement such features or functionality.

Where components or modules of the invention are implemented in whole or in part using software, in one embodiment, these software elements can be implemented to operate with a computing or processing module capable of carrying out the functionality described with respect thereto. One such example computing module is shown in FIG. 15. Various embodiments are described in terms of this example-computing module 300. After reading this description, it will become apparent to a person skilled in the relevant art how to implement the invention using other computing modules or architectures.

Referring now to FIG. 15, computing module 300 may represent, for example, computing or processing capabilities found within desktop, laptop and notebook computers; hand-held computing devices (PDA's, smart phones, cell phones, palmtops, etc.); mainframes, supercomputers, workstations or servers; or any other type of special-purpose or general-purpose computing devices as may he desirable or appropriate for a given application or environment.
